BOTTLE-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 613,836, dated November 8, 1898.

Application filed January 31, 1898. Serial No. 668,594. (No model.)

To aZZ whom it may concern.-

Be it known that I, SAMUEL K. DENNIS, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bottle=Olosures; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.-

The objects of this invention are to provide a bottle-closure which may not be secretly tampered with and which provides for the reclosing of the bottle after it has once been opened.

The invention consists in the various features hereinafter fully described and which are fully illustrated in the accompanying drawings, in which Figure l is an elevation of a bottle provided with myimproved closure. Figs. 2 and 3 are sectional views of the same, taken on the line 2 2 of Fig. 1, Fig. 2 showing the bottle before opening and Fig. 3 showing the position of the parts after the bottle has been once opened and is again closed. Fig. 4 is an elevation of the bottle-neck, taken from the opposite point of view from that of Fig. 1; and Fig. 5 is an elevation of the closing mechanism.

The neck A of the bottle is closed at its extreme end, but is provided with a lateral aperture inclosed by a projecting annular flange B, which is preferably flaring and is provided with an annular instanding rib b. Directly opposite this lateral aperture the neck is provided with a frangible portion, which is preferably formed as a projecting bulb O, which is quite thin at its juncture with the bottleneck, as shown at c c, and comparatively thick elsewhere. This construction provides an annular frangible portion substantially cylindrical in form, so that when the fracture occurs it is accomplished by overcoming the tensile strength of the material rather than by lateral strain, thereby securing a more regular fracture and reducing the liability of the glass to splinter. The strain being outwardly and longitudinal as to the frangible cylindrical portion, any splinters of glass which may result are not likely to fall inwardly.

A stopper I), preferably of cork, is used to close the aperture, being seated within the flange B and being held in its place by the flange 6, past which it must be forced. A screw-threaded spindle E, having a handpiece 6, is passed through the stopper D, being located upon its axis. Near its inner end this spindle is provided with a smooth portion F, adapted to carry a second stopper G, preferably of cork, which is held in place by an enlarged end fof the spindle E. In order to more conveniently pass the large end f of the spindle through the stopper G, it may be tapered and screw-threaded, as shown. The length of the spindle E is such that its inner end may be forced against the bulb C, so as to break out the latter, the pressure of the spindle causing afracture around the base of the bulb, a second lateral aperture X being provided, which may be closed by means of the stopper G. WVhile there is little danger of the bulb breaking up into small fragments, the entrance of any such fragments into the bottle through the aperture X is prevented by the presence of the stopper G.

In order to empty the bottle of its contents, the spindle is turned back after the bulb O has been broken out,- and the discharge is through the aperture X, the recession of the tapering screw-threaded spindle through the stopper D providing an ample vent to allow the free flow of the liquid.

Should the bottle not be entirely emptied of its contents at once, the air may be effectually excluded by again turning up the spindle until the stopper D covers the aperture X, and when in this position the screw-threaded portion of the spindle will entirely close the aperture through which it passes and prevent the entrance of air.

The device serves as a convenient closure for bottles intended for use in vending liquids, such as liquors, and as it cannot be readily refilled serves as a reasonable guaranty of the genuineness of the goods it purports to contain'.

I claim as my invention 1. The combination with a bottle having a lateral aperture in its neck and a frangible portion opposite such aperture, of a stopper for the aperture and a plunger carried by the stopper and controllable from without the bottle for attacking the frangible portion from within the bottle.

2. The combination with a bottle having a lateral aperture in its neck and a frangible portion opposite such aperture, of a stopper for the aperture and a plunger carried by the stopper and controllable from without the bottle for attacking the frangible portion from within the bottle, and a stopper carried by the plunger for closing the aperture produced by rupturing the frangible portion.

3. The combination with a bottle having its neck provided with a lateral aperture and a frangible portion, of a stopper for the aperture, and means carried by the stopper and controllable from without the bottle for attacking the frangible portion from within the bottle.

4. The combination with a bottle having an aperture and a frangible portion, of a stopper securely held within the aperture,and a screw threaded spindle entering the bottle through such stopper and adapted to bear against the frangible portion of the bottle.

5. The combination with a bottle having an aperture and a frangible portion, of a stopper securely held within the aperture, a screwthreaded spindle entering the bottle through such stopper and adapted to bear against the frangible portion of the bottle, and a stopper carried by the spindle for closing the aperture made by the rupture of the frangible portion.

6. The combination with a bottle having a frangible portion, of mechanism for attacking such frangible portion from within the bottle, and a stopper for closing from Within the aperture made by the rupture of such frangible portion.

7. The combination with a bottle having a frangible portion, of mechanism for attacking such frangible portion from Within the bottle, a stopper for closing from Within the aperture made by the rupture of such frangible portion, and means exterior to the bottle for controlling such attacking mechanism and internal stopper.

8. The combination with a bottle having a lateral aperture in its neck and a frangible portion opposite such aperture, of a stopper fixed in such aperture, and a screw-threaded spindle projecting through such stopper and adapted to bear against the frangible portion.

9. The combination with a bottle having a lateral opening in its neck, a flaring flange surrounding such opening and being provided with an instandin g circumferential rib, and having a frangible portion opposite the lateral opening; of a stopper fitting within the flange and secured by the rib, a screwthreaded spindle passing through the stopper and adapted to bear against the frangible portion of the bottle-neck.

10. The combination with a bottle having a lateral opening in its neck and a frangible portion opposite such opening, of a stopper fixed in such opening, a spindle passing through the stopper and in screw-threaded engagement therewith, such spindle having a smooth portion near its innerend and an enlargement beyond such smooth portion, of a valve carried by the smooth portion of the spindle, substantially as described and for the purpose set forth.

11. The combination With a bottle having a lateral opening in its neck and a frangible bulb projecting from the side of the neck opposite the opening, the Walls of the bulb being thin nest near their margins, of a stopper fixed in the opening, and a screw-threaded spindle passing through the stopper and adapted to bear against the inner surface of the bulb.

12. The combination with a bottle having a lateral opening in its neck and a frangible portion opposite such opening, of a stopper fixed in the opening, and a tapering screwthreaded spindle passing through the stopper and adapted to bear against the the frangible portion to rupture it.

In testimony whereof I affix my signature in the presence of two witnesses.
